# Serial Stop

## Overview

![The Serial Stop Node.](https://2561100106-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Ff6JZovzOqBctA4C1o76u%2Fuploads%2Fgit-blob-0204565033b9c045ae2775156a27a406c4362acd%2Fserialstopupdatedimage.png?alt=media)

The **Serial Stop Node** stops the **Serial** connection.

**Serial Communication** in **Incari** is available as a plugin and is enabled as default. However, in the case that it is disabled in the **Plugins Editor**, it will not appear in the **Project Settings** and **Serial Stop** will not show up in the [**Toolbox**](https://docs.incari.com/incari-studio/2023.2/toolbox/overview). Please refer to the [**Plugins Editor**](https://docs.incari.com/incari-studio/2023.2/modules/plugins) to find out more information.

It is important to note that while the **Serial Stop Node** stops a **Serial** connection, it may not completely finish disconnecting from said connection when the **Node** is executed. This could lead to the **Logic** attached to its **Output Pulse** to not work even though there is technically nothing wrong. In order to avoid this, it is highly suggested to use the [**On Serial Stop Node**](https://docs.incari.com/incari-studio/2023.2/toolbox/communication/serial/events/onserialstop) instead. This way, the **Logic** will only execute once the **Serial** connection has definitely been disconnected from. This way, it is assured that the **Logic** will execute once the connection to the **Serial** connection has been terminated.

Again, the user must first use the **Serial Stop Node** to close the connection. Separately, the **On Serial Stop Node** can be used to execute the desired **Communication Logic**.
